Abstract

Disclosed is a dehumidifier capable of dehumidifying an indoor space more efficiently. The present dehumidifier comprises: a body having an intake opening and a discharge opening; a blowing fan arranged inside the body so as to draw air into the body through the intake opening and to discharge the same to the outside through the discharge opening; a fan case having a duct arranged inside the body so as to provide a channel through which the air drawn by the blowing fan flows to the discharge opening; a heat exchanger arranged inside the body so as to remove moisture from the air that has flown into the body; and fixed blades that are fixedly installed inside the duct so as to split the air, which has flowed through the channel, to a plurality of discharge paths.

First claim

The invention claimed is:

1. A dehumidifier comprising:
a body having an intake opening and a discharge opening;
a blowing fan arranged inside the body and configured to draw air into the body through the intake opening and to discharge the air to an outside through the discharge opening;
a fan case arranged inside the body and provided with a duct forming a channel through which the air drawn by the blowing fan flows to the discharge opening; and
a plurality of fixed blades fixedly installed inside the duct and configured to split the air, which flows through the channel, to a plurality of discharge paths, each of the fixed blades comprising:
a front fixed side having a curved shape corresponding to a front curvature angle, and
a rear fixed side having a curved shape corresponding to a rear curvature angle, the rear curvature angle being less than the front curvature angle,

wherein the duct comprises a first slope part having a shape sloping upwards to the discharge opening, the first slope part having a first slope angle from an upward direction, and a second slope part that is arranged opposite to the first slope part, the second slope part having a second slope angle from the upward direction, the second slope angle that is more acute than the first slope angle, and
wherein the front fixed side of each of the fixed blades is arranged to face the first slope part and is convex toward the first slope part, and the rear fixed side of each of the fixed blades is arranged to face the second slope part and is concave toward the second slope part.

2. The dehumidifier of claim 1 , wherein the fixed blades are arranged across a width direction of the discharge opening.

3. The dehumidifier of claim 2 , wherein the fixed blades have preset heights toward the discharge opening and are arranged to be parallel with one another.

4. The dehumidifier of claim 2 , wherein the discharge opening is provided in an upper surface of the body above the plurality of fixed blades, and upper ends and lower ends of the fixed blades are arranged to be off-center to one another.

5. The dehumidifier of claim 4 , wherein:
the duct has a shape of which a cross-sectional area increases upwards.

6. The dehumidifier of claim 1 , further comprising:
a dispersion plate that is arranged on sides of the fixed blades inside the duct and has a plurality of dispersion holes through which air flowing through the fixed blades is dispersed.

7. The dehumidifier of claim 6 , wherein the dispersion holes are hexagonal shapes, and the dispersion plate is formed in a honeycomb structure.

8. The dehumidifier of claim 1 , further comprising:
a rotating blade that is arranged to a side of each of the fixed blades and configured to change a discharge direction of air that flows through the fixed blades.

9. The dehumidifier of claim 8 , wherein the discharge opening is formed in an upper surface of the body above the plurality of fixed blades, and the rotating blade is arranged across a width direction of the discharge opening.

10. The dehumidifier of claim 9 , wherein the rotating blade includes a plurality of rotating blades, and the rotating blades have preset heights along upward and downward directions and are arranged to be parallel with one another.

11. The dehumidifier of claim 9 , further comprising a communication opening formed in an upper surface of the duct below the discharge opening and fluidly connected to the discharge opening,
wherein the fixed blades are arranged at preset distances along a longitudinal direction of the communication opening and have preset heights along an upward and downward direction, and
wherein a number of rotating blades is equal to or smaller than a number of the fixed blades.

12. The dehumidifier of claim 10 , further comprising:
a plurality of rotation axes that are respectively axially combined with the rotating blades and are rotatably supported by the duct;
a motor that is connected to at least one of the rotation axes and configured to rotate the at least one of the rotation axes; and
a link member that is arranged under the rotation axes and connected to the rotating blades.

13. The dehumidifier of claim 12 , wherein the rotating blades are arranged under the rotation axes and have projections projecting from the rotating blades, and
wherein the link member is arranged perpendicular to the rotating blades and has fixing holes into which the projections are inserted and rotatably supporting the projections.

14. The dehumidifier of claim 12 , wherein the rotating blades rotate in one direction by a driving force of the motor to position in a first position where upper ends of the rotating blades are off-center to sides of lower ends of the rotating blades, and rotate in an opposite direction to switch to a second position where the upper ends of the rotating blades are off-center to other sides of the lower ends of the rotating blades.

15. A dehumidifier comprising:
a body having an intake opening and a discharge opening;
a blowing fan arranged inside the body and configured to draw air into the body through the intake opening and to discharge the air to an outside through the discharge opening;
a fan case arranged inside the body and provided with a duct forming a channel through which the air drawn by the blowing fan flows to the discharge opening;
fixed blades fixedly installed inside the duct and configured to split the air, which flows through the channel, to a plurality of discharge paths, each of the fixed blades comprising:
a front fixed side having a curved shape corresponding to a front curvature angle, and
a rear fixed side having a curved shape corresponding to a rear curvature angle, the rear curvature angle being less than the front curvature angle;

rotating blades arranged in the duct above the fixed blades and configured to change a discharge direction of air that flows through the fixed blades; and
a dispersion plate arranged between the fixed blades and the rotating blades and having a plurality of dispersion holes through which the air split by the fixed blades is dispersed,
wherein the duct comprises a first slope part having a shape sloping upwards to the discharge opening, the first slope part having a first slope angle from an upward direction, and a second slope part that is arranged opposite to the first slope part, the second slope part having a second slope angle from the upward direction, the second slope angle that is more acute than the first slope angle, and
wherein the front fixed side of each of the fixed blades is arranged to face the first slope part and is convex toward the first slope part, and the rear fixed side of each of the fixed blades is arranged to face the second slope part and is concave toward the second slope part.
